WebBacterial Transformation; Picking Colonies; Freezing Bacteria; Making Competent Cells (Inoue Method) Inoue and colleagues developed this method in 1990. It works well for many strains commonly used in cloning. The original method calls for growing the overnight E. coli cultures at 18 °C. We find that it still works well if they are grown ... WebTransformation is a key process in molecular cloning, by which multiple copies of recombinant DNA molecules are produced. The ability to take up free, extracellular genetic material is the prerequisite for bacterial …

Cloning and expression vector construction of MhPSY1 gene. Webas assessed by transformation efficiency and mitotic stability. Both fragments were found to be rich in AT content (69.5% and 70.8% respectively), and to contain an 11-bp ARS consensus sequences (10 and 13 motifs with one base difference respectively). Using the ARS-containing plasmid as a promoter-cloning vector, sev-
WebTransformation efficiency is typically 1–3 orders of magnitude lower than the equivalent electrocompetent cells Ideal for producing large, high-diversity libraries Higher transformation efficiencies compared to the equivalent chemically competent cells, increasing success in difficult cloning applications WebTroubleshooting Guide for Cloning. Transform 100 pg–1ng of uncut vector to check cell viability, calculate transformation efficiency and verify the antibiotic resistance of the plasmid. Transform the cut vector to determine the amount of background due to undigested plasmid. The number of colonies in this control should be <1% of the number ...
